Question

我想做代码，无论我的iPhone是否与互联网连接，无论是wifi还是蜂窝网络。

现在我的问题是当我通过蜂窝连接执行我的应用程序时，我没有收到任何错误和应用程序运行和Web服务调用正常工作但是当我将互联网连接从蜂窝网络切换到wifi网络时，我得到警告＆＃34 ;没有互联网连接＆＃34;即使intetnet在wifi上正常工作。

你能帮助我找到这个问题吗？

代码：

在viewDidLoad（）中，我正在调用此函数：

callWSForGetProjectLeadersList()

在以下功能中，我正在检查互联网连接是否可用：isConnectedToNetwork（）

func callWSForGetProjectLeadersList()
{
    if Reachability.isConnectedToNetwork()
    {
        DispatchQueue.global(qos: DispatchQoS.QoSClass.default).async {
            do
            {
                try WebServiceCall.webServiceCall("getUsers", parameters: nil, tag: "getUsers", reference: self, type: "POST")
            }
            catch
            {
                CommonFunctions.exceptionAlert()
                return
            }
        }
    }
    else
    {
        // TODO : This is part should not run while Internet connection is avail.
        DispatchQueue.main.async(execute: {
            ActivityIndicator.stopAnimating()
            Toast.showMessage(self.view, msg: "Please check your internet connection and try after sometime", time: 2.0)
        })
    }
}

现在在具有ToCheck Internet连接的以下类代码中：

public class Reachability {

class func isConnectedToNetwork() -> Bool {

    var zeroAddress = sockaddr_in(sin_len: 0, sin_family: 0, sin_port: 0, sin_addr: in_addr(s_addr: 0), sin_zero: (0, 0, 0, 0, 0, 0, 0, 0))
    zeroAddress.sin_len = UInt8(MemoryLayout.size(ofValue: zeroAddress))
    zeroAddress.sin_family = sa_family_t(AF_INET)

    let defaultRouteReachability = withUnsafePointer(to: &zeroAddress) {
        $0.withMemoryRebound(to: sockaddr.self, capacity: 1) {zeroSockAddress in
            SCNetworkReachabilityCreateWithAddress(nil, zeroSockAddress)
        }
    }

    var flags: SCNetworkReachabilityFlags = SCNetworkReachabilityFlags(rawValue: 0)
    if SCNetworkReachabilityGetFlags(defaultRouteReachability!, &flags) == false {
        return false
    }

    /* Only Working for WIFI
     let isReachable = flags == .reachable
     let needsConnection = flags == .connectionRequired

     return isReachable && !needsConnection
     */

    // Working for Cellular and WIFI
    let isReachable = (flags.rawValue & UInt32(kSCNetworkFlagsReachable)) != 0
    let needsConnection = (flags.rawValue & UInt32(kSCNetworkFlagsConnectionRequired)) != 0
    let ret = (isReachable && !needsConnection)

    return ret

}

当我在wifi上运行时，它会调用以下函数：

class func networkAlert()
{
    DispatchQueue.main.async(execute: {
        let alert = UIAlertView(title: "No Internet!", message: "No working Internet connection is Found.", delegate: nil, cancelButtonTitle: "Ok")
        alert.show()
    })
}

wifi连接工作正常仍然给错误，互联网连接不可用
